[. . . ] The Rockford Fosgate trademark is owned by, and is used under a license from, Rockford Corporation, Tempe Arizona, USA. [. . . ] For safety, disconnect the negative lead from the battery prior to beginning the installation. For easier assembly, we suggest you run all wires prior to mounting your monitor in place. Use high quality connectors for a reliable installation and to minimize signal or power loss. Be careful not to cut or drill into gas tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on any vehicle. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall. Be sure that the mounting location is deep enough for the monitor to fit; if mounting in a door, operate all functions (windows, locks, etc. ) through their entire operating range to ensure there is no obstruction. Refer to the section "dimensions" to determine the proper cutout hole to cut for your monitor model.
